    Glad you got it sorted. Make sure you post some pics and give us updates on your build process :) Regards Jerry

    No actually I didn't, thanks :o No option of course if I want the radial build to be all spoke heads facing out. Thanks Jerry

    New Super Light Tongxin Motor Design/Kit

    I will probably lace it radial. The only problem is the countersinks are drilled deeper every alternatate hole either side of the flange, assuming you will be doing one spoke head in and one out for lacing. I may have to do the radial with each spoke head alternating in and out as the...

    New Super Light Tongxin Motor Design/Kit

    I had a question about the flange thickness and possible problem with the spoke lying over them when laced. Although it looks like the flange is wider on the Goldant it isn't. Both are approx 6mm wide. The shamfer is just less on the Goldant compared to the Nano. Goldant Nano Here it...

    Ezee battery Vs Crystalyte Vs Cellman Lifepo4

    I never really knew they existed when I started and the A123s where more readily available at the time. I don't see the point of switching now as I would have to change my bulk chargers for the 3.7v cells. I am also pretty sure those cells in one series strings would not be as reliable. Ps...

    Ezee battery Vs Crystalyte Vs Cellman Lifepo4

    My Brompton is magic and has fairy dust in the frame :p Seriously its pretty flat in Cambridge. My commute is 5.25 miles. I only use throttle to get me moving and assist up to 15mph and then switch it off and pedal. On still calm days I can average 17mph on the flat and easily hit 20mph plus if...

    Ezee battery Vs Crystalyte Vs Cellman Lifepo4

    If you suspect a failed cell you would need to measure the voltage of each cell after a bike ride! The dodgy cell would have dropped to below 2.0v. Then again another indication is that the BMS would cut the power early because of low voltage. To be honest if the A123 packs you are looking at...

    Do members think rear suspension a good idea on a pedelec?

    Again its horses for courses but I think small wheeled bike benefit greatly from suspension, more so on the rear than the front. Never tried a sprung seatpost. Jerry

    New Super Light Tongxin Motor Design/Kit

    No problem and thanks Neptune. I actually really enjoy posting and including lots of pics. In the past I have found that posts with lots of pictures help me understand what is going on. It also helps form part of my thinking process as my projects progress. You are also right to highlight my...

    Ezee battery Vs Crystalyte Vs Cellman Lifepo4

    Well he will no doubt spot weld tabs from one cell to another. Buy a few A123 cells with single tabs spot welded onto them. If a cell fails then cut the old cell out and solder in a new one. My current 3500 mile, 29 month old pack has had two cells replaced. Not easy/simple and any BMS...

    Ezee battery Vs Crystalyte Vs Cellman Lifepo4

    Benjy, Might add too if he is using the cylindrical A123 cells it would be easier to replace a failed cell as well, though I think he uses pouch A123 cells now. Regards Jerry

    New Super Light Tongxin Motor Design/Kit

    Close up of pedelec arrangement I asked about using an existing Tongin controller so I can use my throttle preference and was told this controller is an upgrade in terms of it running the motor better without the start glitches that sometimes occur with the current one. I will probably...

    New Super Light Tongxin Motor Design/Kit

    Two wires coming out of each end means limited functionality : 1. Power 2. Pedelec 3. Brake Cutout/Switch.. glad this has been included. 4. Motor This is the wiring diagram I got from them when I asked.

    New Super Light Tongxin Motor Design/Kit

    Ok the controller, again very different from the normal offering. End profile shows curved presumably to enable it to be easily strapped to frame tubing.

    Ezee battery Vs Crystalyte Vs Cellman Lifepo4

    Hech is correct and raises another benefit I had over looked. A123 cells are rated at up to 30C constant and 60C peak. So each 2.3Ah cell can be discharged at 69amps constant and 138amp peak. Not much point in using that in a smaller pack given that you would exhaust them in minutes at those...

    Financial Wealth

    Seems like a good place to post this link. BBC iPlayer - One to One: Lucy Kellaway with Anon I came across this link in the Brompton forum. You will see why it was posted there when you listen to it. More of interest is the general discussion. Parts are a little aloof but on the whole I found...

    Happy ?

    Wow clearly I have been missing out on a whole other side to you guys/gal. Having suffered from deep depression quite a few years ago (just to keep it cheery), I have learnt that happiness is often over rated. It comes and goes. I much prefer the idea of continual contentment. By that I mean...
